the aim of this study was to evaluate the effect of chlorhexidine (chx) application on immediate and two-month bond strength of a filled adhesive system. methods: forty eight non-carious human third molars without enamel of occlusal surface were randomly divided into two main groups according to chx application: control and chx. each main group was further subdivided into 2 subgroups depending ...

AIM This study evaluated the effect of filler existence in self-etch adhesive resin on the marginal leakage of a class V restoration. MATERIALS AND METHODS Class V cavities were prepared and restored with a resin composite on the buccal surfaces of 48 premolars lined with unfilled or filled adhesives (n = 24). After thermo cycling, teeth in each group were divided to two subgroups (n = 12), s...

Current technology, Inkjet is an accepted technology for dispensing small volumes of material (50 – 500 picolitres). Currently traditional metal-filled conductive adhesives cannot be processed by inkjetting (owing to their relatively high viscosity and the size of filler material particles). Smallest droplet size achievable by traditional dispensing techniques is in the range of 150 μm, yieldin...

PURPOSE The purpose of this study was to compare the in vitro microleakage of fourth-generation filled and unfilled adhesive resin systems with fifth-generation filled and unfilled adhesive resin systems in both primary and permanent teeth. METHODS Eighty extracted or exfoliated human noncarious teeth (40 primary and 40 permanent) were assigned to each of 8 groups. Groups 1, 3, 5 and 7 were p...

background and aims. effect of surface treatments on repair bond strength of aged composite resins might be different due to their dissimilar fillers. the aim was to evaluate the effect of different surface treatments on repair micro-shear bond strength (µsbs) of silica- (spectrum tph) and zirconia-filled (filtek z250) composite resins. materials and methods. twenty-seven composite resin blocks...

Cellulose nanofibrils were prepared by mechanical fibrillation of never-dried beech pulp and bacterial cellulose. To facilitate the separation of individual fibrils, one part of the wood pulp was surface-carboxylated by a catalytic oxidation using (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) as a catalyst. After fibrillation by a high pressure homogenizer, the obtained aqueous fibril dispers...

AIM This study tested the null hypothesis that there is no difference on microleakage of dentin-bordered composite restorations using single or double coats of adhesive from one-bottle adhesive systems. METHODS AND MATERIALS The enamel surface was removed from freshly extracted bovine teeth, and standardized Class V cavities (3 x 3 x 1.5 mm) were made at the cervical areas of buccal surfaces....
